PERL filtering...

[John W. Lemons III]

I have recently deployed a freeware procmail script that does a very good
job filtering out various forms or malicious mail.  So far it has caught all
the ILOVEYOU mail and a few of the variants we have seen.  Since I use QMail
on my own machine, can procmail scripts be used with QMail?  Most of the
script uses some well crafted PERL code, so if not, it could probably be
shoe-horned into a form that QMail will utilize.  Any suggestions?
